Sildenafil is a prescription medication used to treat erectile dysfunction and pulmonary arterial hypertension. In most people, an erection occurs when the blood vessels in the penis relax and become engorged with blood. However, in men who suffer from erectile dysfunction, this does not happen. Sildenafil is a phosphodiesterase-5 (PDE5) inhibitor, which means it prevents a specific enzyme from breaking down another enzyme that allows for blood flow to increase in the penis during sexual stimulation. To help understand what Sildenafil is and its potential benefits, read the article below.

What Is Sildenafil?

Sildenafil is a phosphodiesterase type 5 inhibitor. PDE 5 inhibitors relax muscles in the blood vessels and increase blood flow to particular areas of the body. Sildenafil is taken to treat erectile dysfunction in men. It does not cure erectile dysfunction but can improve certain aspects of sexual function. The drug's effectiveness will rely on how long one takes Sildenafil, and how often one takes it.

Sildenafil is commonly used for treating the condition of erectile dysfunction in men. Sildenafil can be taken as a tablet that is swallowed with a glass of water, or as a sublingual tablet that is usually kept under the tongue and allowed to dissolve. Sildenafil can also be taken as a liquid that is injected into a muscle.

Avoid taking Sildenafil if a person is under medication or also taking nitrate drugs for chest pain or heart problems. Also avoid taking Sildenafil along with the drugs like Nitroglycerin, Isosorbide dinitrate, Isosorbide mononitrate, and some other recreational drugs. Taking Sildenafil with nitrate medicine leads to a severe decrease in blood pressure. It may also cause dizziness and lightheadedness upon standing up after sitting or lying down.

How Does Sildenafil Work?

Erectile dysfunction (ED) is a common condition that occurs when a man has trouble getting or keeping an erection. It can be caused by psychological or physical factors, including aging, certain chronic diseases, or the use of certain prescription medications. It is also used to treat PAH (pulmonary arterial hypertension) in women with sexual dysfunction. When a person is sexually aroused, Sildenafil helps the blood vessels relax and widen so blood can flow into the body and cause an erection. Sildenafil relaxes muscles in the body, including those in the penis. It is not known exactly how Sildenafil works in women to treat sexual dysfunction. It is thought to work by increasing blood flow to the pelvic area.

What Are the Benefits of Sildenafil?

  • One of the most common reasons for taking Sildenafil is to treat the disease of erectile dysfunction. Erectile dysfunction is a common condition in which men can experience difficulty getting or maintaining an erection. It affects around one in 10 men aged between 40 and 70.

  • When administered to patients who have had a heart attack, Sildenafil can decrease the risk of death and the risk of having a second heart attack.

  • Sildenafil may increase the chance of survival in patients who have suffered a heart attack.

  • The benefits of Sildenafil extend beyond erectile dysfunction. Sildenafil has been proven to be effective for many different conditions. Sildenafil can also be used to prevent blood clots when given to patients who are undergoing surgery.

Sildenafil should also not be taken if one is taking any other medications. Men who are taking Sildenafil should avoid consuming grapefruit while taking the drug. Grapefruit can increase the amount of Sildenafil in the bloodstream by almost 50 percent. This can increase the risk of side effects. Women who are taking Sildenafil should avoid taking certain medications. These include certain antibiotics, HIV (human immunodeficiency) drugs, anti-epileptic medications, and anti-cancer medications.

What Is the Dosage of Sildenafil?
